Upgrade a domain that consists of multiple instances of BlackBerry UEM
If the recommended upgrade path is to upgrade
UEMversions in stages, then you must upgrade all instances to the first stage, restart them, and upgrade them all to the second stage. For example, if you are running
UEMversion 12.11, you must upgrade all instances by two
UEMversions at a time to the latest
If you’re upgrading your environment in stages, test your environment after each stage of the upgrade to make sure everything is working as expected. If it is not, resolve any issues before proceeding to the next stage of the upgrade.
- If the upgrade path is fromBlackBerry UEMversion 12.9.1 or earlier, shut down all instances ofUEMin the domain.
- Upgrade oneUEMcore instance.The setup application also backs up and upgrades theUEMdatabase. After the upgrade, theUEMinstance starts automatically.When you upgrade a core instance, you must use an upgraded management console instance to connect to that core and manage the domain.
- Upgrade the otherUEMcore or management console instances. You can upgrade these remainingUEMinstances more than one at a time.
- Upgrade anyBlackBerry Connectivity Node-only instances (that contain only the device connectivity components) last. You can upgrade more than oneBlackBerry Connectivity Node-only instance at a time.
